| 摘 要： | 在对锚杆(索)作用机理及其对岩体作用力学效应分析的基础上，研究了锚杆(索)受力及变形特性，探讨了在锚杆支护中使用碟形托盘及其组合体进行让压支护的可行性，使支护体在高应力大变形或瞬间冲击荷载下，在确保锚杆承载力不受影响前提下有一定变形，通过释放部分应力来实现减少或避免锚杆破断，有效地提高锚杆的支护效果。

| Abstract: | Based on anchor bolt (cable) mechanism and analysis of the action of anchor bolt (cable) on rocks mechanical effects, the paper studied the force and deformation characteristics of anchor bolt (cable), explored the feasibility of the use of the disc tray combination for yield supporting on bolting supporting.Under high stress, large deformation and impact load, the bolt capacity is not affected in the premise of ensuring that supporting body had certain deformation, through release of some stress, bolt breaking was reduced and avoided, effectively improving bolt support effect. |
